Nuke lots of obsolete compiler versions

Make gcc4 depend on !LINUX_2_4 - I'm getting sick of seeing people complain about
compile errors when trying to build brcm-2.4 with it.

-# Description:
-#
-# Nicholas Pitre released this patch for gcc soft-float support here: 
-# http://lists.arm.linux.org.uk/pipermail/linux-arm/2003-October/006436.html
-#
-# This version has been adapted to work with gcc 3.4.0.
-#
-# The original patch doesn't distinguish between softfpa and softvfp modes
-# in the way Nicholas Pitre probably meant.  His description is:
-#
-# "Default is to use APCS-32 mode with soft-vfp.  The old Linux default for
-# floats can be achieved with -mhard-float or with the configure
-# --with-float=hard option.  If -msoft-float or --with-float=soft is used then
-# software float support will be used just like the default but with the legacy
-# big endian word ordering for double float representation instead."
-#
-# Which means the following:
-#
-# * If you compile without -mhard-float or -msoft-float, you should get
-#   software floating point, using the VFP format.  The produced object file
-#   should have these flags in its header:
-#
-#     private flags = 600: [APCS-32] [VFP float format] [software FP]
-#
-# * If you compile with -mhard-float, you should get hardware floating point,
-#   which always uses the FPA format.  Object file header flags should be:
-#
-#     private flags = 0: [APCS-32] [FPA float format]
-#
-# * If you compile with -msoft-float, you should get software floating point,
-#   using the FPA format.  This is done for compatibility reasons with many
-#   existing distributions.  Object file header flags should be:
-#
-#     private flags = 200: [APCS-32] [FPA float format] [software FP]
-#
-# The original patch from Nicholas Pitre contained the following constructs:
-#
-#   #define SUBTARGET_EXTRA_ASM_SPEC "%{!mcpu=*:-mcpu=xscale} \
-#     %{mhard-float:-mfpu=fpa} \
-#     %{!mhard-float: %{msoft-float:-mfpu=softfpa;:-mfpu=softvfp}}"
-#
-# However, gcc doesn't accept this ";:" notation, used in the 3rd line.  This
-# is probably the reason Robert Schwebel modified it to:
-#
-#   #define SUBTARGET_EXTRA_ASM_SPEC "%{!mcpu=*:-mcpu=xscale} \
-#     %{mhard-float:-mfpu=fpa} \
-#     %{!mhard-float: %{msoft-float:-mfpu=softfpa -mfpu=softvfp}}"
-#
-# But this causes the following behaviour:
-#
-# * If you compile without -mhard-float or -msoft-float, the compiler generates
-#   software floating point instructions, but *nothing* is passed to the
-#   assembler, which results in an object file which has flags:
-#
-#     private flags = 0: [APCS-32] [FPA float format]
-#
-#   This is not correct!
-#
-# * If you compile with -mhard-float, the compiler generates hardware floating
-#   point instructions, and passes "-mfpu=fpa" to the assembler, which results
-#   in an object file which has the same flags as in the previous item, but now
-#   those *are* correct.
-#    
-# * If you compile with -msoft-float, the compiler generates software floating
-#   point instructions, and passes "-mfpu=softfpa -mfpu=softvfp" (in that
-#   order) to the assembler, which results in an object file with flags:
-#
-#   private flags = 600: [APCS-32] [VFP float format] [software FP]
-#
-#   This is not correct, because the last "-mfpu=" option on the assembler
-#   command line determines the actual FPU convention used (which should be FPA
-#   in this case).
-#
-# Therefore, I modified this patch to get the desired behaviour.  Every
-# instance of the notation:
-#
-#   %{msoft-float:-mfpu=softfpa -mfpu=softvfp}
-#
-# was changed to:
-#
-#   %{msoft-float:-mfpu=softfpa} %{!msoft-float:-mfpu=softvfp}
-#
-# I also did the following:
-# 
-# * Modified all TARGET_DEFAULT macros I could find to include ARM_FLAG_VFP, to
-#   be consistent with Nicholas' original patch.
-# * Removed any "msoft-float" or "mhard-float" from all MULTILIB_DEFAULTS
-#   macros I could find.  I think that if you compile without any options, you
-#   would like to get the defaults. :)
-# * Removed the extra -lfloat option from LIBGCC_SPEC, since it isn't needed
-#   anymore.  (The required functions are now in libgcc.)
